Description

Technical Field

[0001] This invention belongs to the field of composite functional textile technology, specifically a moisture-wicking, quick-drying, and easy-to-clean functional fabric. Background Technology

[0002] After exercise, the human body sweats profusely. To avoid a stuffy and sticky feeling, clothing made with moisture-wicking and quick-drying fabrics can quickly absorb and transfer sweat, keeping the skin dry and comfortable. Meanwhile, clothing worn in daily life, especially some synthetic fiber fabrics, is particularly prone to getting dirty, and their oleophilic nature makes them difficult to clean. However, some easily stain-resistant fabrics can be easily cleaned with ordinary washing methods. It is understood that achieving easy stain removal in fabrics mostly relies on post-processing, while the moisture-wicking and quick-drying function is achieved by modifying the fibers through physicochemical methods to change their structural properties and fabric structure, or by combining them with other fibers and using finishing agents. Many products have only one function. For example, using organic fluorine finishing agents to treat silk fabrics makes them easier to wash, thus meeting consumer demand. DuPont's Coolmax fiber has a flat, cross-shaped cross-section, giving the fiber and its fabric moisture-wicking and quick-drying properties.

[0003] Today, China has become a major producer and consumer of textiles. While people enjoy convenient lifestyles, the improper disposal of many non-biodegradable textile wastes has led to environmental degradation. Textiles woven from biodegradable fibers can precisely address this problem. Currently, biodegradable textile fibers are categorized into natural biodegradable fibers (cotton, linen, silk, etc.), recycled biodegradable fibers (modal, viscose, milk protein fiber, etc.), and synthetic biodegradable fibers (PLA, PCL, PHA, etc.). Furthermore, biodegradable fiber blends exhibit excellent performance; for example, milk protein and Tencel blends demonstrate good breathability, bursting strength, and dimensional stability. PLA / PHBV blended filaments and viscose filament blends possess antibacterial properties and a smooth hand feel.

[0004] For the reasons mentioned above, it is necessary to provide a biodegradable interwoven fabric that combines moisture absorption and quick drying with easy stain removal. Summary of the Invention

[0005] In view of the above situation and to overcome the existing defects, the present invention provides a moisture-wicking, quick-drying and easy-to-clean functional fabric with warp yarns made of mulberry silk and weft yarns made of viscose staple fiber or celestine biodegradable staple fiber. This fabric has excellent moisture-wicking, quick-drying and easy-to-clean properties, which not only meets consumers' demand for functional fabrics, but also solves the problem of poor biodegradability of ordinary polyester fabrics.

[0006] The present invention provides the following technical solution: The present invention proposes a moisture-wicking, quick-drying, and easy-to-clean functional fabric, specifically an A-series sample. The A-series sample is a five-end satin woven fabric. The warp yarn of the A-series sample is a yarn made of two mulberry silks with a linear density of 22.2~24.4 dtex and a twist of 600 twists / m. The weft yarn of the A-series sample is selected from weft yarn one and weft yarn two with different weft ratios. Weft yarn one is a celes short fiber yarn with a linear density of 118 dtex and a twist of 91 twists / 10cm. Weft yarn two is a viscose short fiber yarn with a linear density of 118 dtex and a twist of 105 twists / 10cm. Both the celes short fiber yarn and the viscose short fiber yarn are spun by compact Sirospun spinning.

[0007] Furthermore, the warp density of the A-series samples is 110 threads / cm, and the weft density of the A-series samples is 58 threads / cm.

[0008] Furthermore, the weft ratio of weft yarn one and weft yarn two can be selected from any of the following ratios: (0:1), (1:4), (1:3), (1:2), (1:1), (2:1), (3:1), (4:1) and (1:0).

[0009] Furthermore, the thicknesses of the samples for each of the aforementioned weft projection ratios are 0.25 mm, 0.25 mm, 0.25 mm, 0.25 mm, 0.26 mm, 0.26 mm, 0.26 mm, 0.26 mm, and 0.27 mm, respectively.

[0010] This invention also proposes a moisture-wicking, quick-drying, and stain-resistant functional fabric, specifically a B-series sample. The warp yarn of the B-series sample is a yarn made by twisting two mulberry silks with a linear density of 22.2~24.4 dtex at a twist of 600 twists / m. The weft yarn of the B-series sample includes weft yarn one and weft yarn two, with a weft ratio of 1:1. Weft yarn one is a celesite staple fiber yarn with a linear density of 118 dtex and a twist of 91 twists / 10cm, and weft yarn two is a viscose staple fiber yarn with a linear density of 118 dtex and a twist of 105 twists / 10cm. Both the celesite staple fiber yarn and the viscose staple fiber yarn are spun using compact Sirospun technology.

[0011] Furthermore, the warp density of the B series samples is 110 threads / cm, and the weft density of the B series samples is 55 threads / cm.

[0012] Furthermore, the microstructure of the B series samples is selected from any of the following microstructures: 2 / 1 twill, four-end twill, five-end satin, eight-end satin, and honeycomb.

[0013] Furthermore, the thicknesses of the samples corresponding to each tissue structure are 0.21 mm, 0.24 mm, 0.26 mm, 0.31 mm and 0.62 mm, respectively.

[0014] The beneficial effects of the present invention using the above structure are as follows: The present invention proposes a moisture-wicking, quick-drying, and easy-to-clean functional fabric. By using mulberry silk as the warp yarn and viscose and Celesin biodegradable polyester fiber as the weft yarn, an environmentally friendly fabric that is both moisture-wicking and quick-drying and easy to clean is developed. This solves the problem of poor biodegradability of ordinary polyester fabrics while meeting consumers' demand for functional fabrics.

[0015] Furthermore, by controlling the content of functional fibers (viscose and celery) in the weft yarns and the resulting changes in fabric structure, the following conclusions were drawn:

[0016] 1) When the content of biodegradable Ceres fiber in the weft yarn changes, while other fabric parameters remain the same, as the content of biodegradable Ceres fiber increases, the water droplet diffusion time of the sample decreases, while the wicking height and evaporation rate increase. Although the water absorption rate and moisture permeability do not change significantly, they all meet the national standards for quick-drying fabrics. When the fabric structure changes, while other fabric parameters remain the same, the eight-end satin weave exhibits the best quick-drying performance.

[0017] 2) The stain-removing properties of fabrics improve with the increase of the content of celery biodegradable fiber in the weft yarn, and fabrics with smooth surface are easier to clean than fabrics with uneven surface. Attached Figure Description

[0025] Table 1 Sample Specifications

[0026]

[0027] II. Equipment

[0028] GeminiSEM500 field emission scanning electron microscope (Zeiss AG, Germany), YG(B)141D digital fabric thickness gauge (Wenzhou Darong Textile Instrument Co., Ltd.), A2204C electronic balance (Qingdao Juchuang Environmental Protection Group Co., Ltd.), timer, burette, beaker, tertiary water, YG(B)871 capillary effect measuring instrument (Wenzhou Darong Textile Instrument Co., Ltd.), YG601-I / II computerized fabric moisture permeability meter (Ningbo Textile Instrument Factory), anhydrous calcium chloride, moisture permeation cup, silica gel desiccant, absorbent filter paper dropper, glass rod, soy sauce, cotton standard lining (commercially available).

[0029] III. Testing Methods

[0030] This article focuses on exploring the moisture absorption, quick-drying properties, and stain-removing properties of fabrics. Therefore, the above two tests were first conducted on fabric samples of series A and B, and the test results were then analyzed and summarized.

[0031] 3.1 Moisture absorption and quick-drying performance and stain removal performance test

[0032] Moisture absorption and quick-drying properties are divided into moisture absorption and quick-drying properties. Moisture absorption is further categorized into water absorption rate, water droplet diffusion time, and wicking height, while quick-drying properties are categorized into moisture evaporation rate and moisture permeability. Before testing, the fabrics are subjected to 24 hours of temperature and humidity equilibration according to regulations.

[0033] 3.1.1 Hygroscopicity Test

[0034] The water absorption rate was tested according to GB / T21655.1-2008 "Textiles - Evaluation of Moisture Absorption and Quick-drying - Part 1: Single Combination Test Method". Five samples with a length and width of 110 mm were cut for each sample and immersed in grade III water. After 5 minutes, the samples were removed and the fabric was kept flat and hung vertically to allow water droplets to fall. The samples were weighed when the time interval between two adjacent drops was not less than 30 seconds, and the average value was calculated.

[0035] The water diffusion time test was also conducted according to the national standard for water absorption rate. Five samples, each 110 mm in length and width, were cut from each sample and laid flat on the table. Then, a small amount of grade III water was drawn up with a burette, with the nozzle no more than 10 mm away from the sample surface, and 0.2 mL of water was dropped onto the sample. The time taken for the water to completely diffuse on the sample surface was recorded, and the average time was taken.

[0036] The wicking height test was conducted according to FZ / T01071—2008 "Test Method for Capillary Effect of Textiles". Three samples, approximately 250 mm long and 30 mm wide, were cut along both the warp and weft directions of each sample. These samples were mounted on a YG(B)871 capillary effect measuring instrument, with the lower end of the sample positioned (15±2) mm below the zero point of the scale. After 30 minutes, the lowest wicking value in each warp and weft direction was measured. The average value in each direction was calculated, and the larger value in the warp and weft directions was taken.

[0037] 3.1.2 Quick-drying test

[0038] The national standard for moisture evaporation rate and water absorption rate testing is the same. Immediately weigh the sample after the droplet diffusion test is completed. Then keep the sample surface flat and hang it vertically in the standard atmosphere. Weigh and record the weight every 3 minutes. When the mass change rate between two consecutive tests is not higher than 1%, the experiment is terminated.

[0039] The moisture permeability was tested according to GB / T12704.1—2009 "Textiles - Test Methods for Moisture Permeability of Fabrics - Part 1: Moisture Absorption Method". Three specimens with a radius of 35 mm were prepared for each sample. These specimens, along with anhydrous calcium chloride and a permeation cup, were assembled into a permeation assembly as required. The assembly was then placed in a YG601-Ⅰ / Ⅱ permeabilizer with the temperature and humidity adjusted as specified. After 1 hour, the assembly was removed, the cup lid was replaced, and the assembly was dried for 0.5 hours before weighing. The assembly was then gently shaken to prevent the effectiveness of the desiccant in the uppermost layer from decreasing over time. Finally, the cup lid was removed, and the assembly was placed back into the permeabilizer to repeat the previous experimental procedures.

[0040] 3.1.3 Easy-to-clean performance test

[0041] According to FZ / T001118-2012 "Detection and Evaluation of Stain Repellency of Textiles - Wiping Method for Stain Removability", the stain repellency was tested.

[0042] First, place filter paper under the flat cloth sample. Then, using a dropper, drop approximately 0.5 mL of high-salt, dilute-state fermented soy sauce (meeting GB / T18186—2000 "Brewed Soy Sauce") onto the cloth sample. Next, use a glass rod to evenly spread the liquid within a 5 mm radius circle. Allow the cloth sample to dry flat. Use a color chart to assess the initial color difference between the stained and unstained areas. Then, use a cotton pad with an 85% ± 3% liquid content to wipe the stained area of ​​the cloth sample in one direction. After each wipe, replace the cotton pad with a clean pad and repeat 30 times. Finally, use a color chart to assess the color difference between the wiped and unstained areas.

[0043] 3.2 Degradation test of Celes fiber in natural soil

[0044] One gram of Celes short fiber yarn and one gram of ordinary polyester yarn were buried in the soil of a campus forest for three months. The degradation degree of Celes biodegradable fiber and polyester fiber was then observed using a GeminiSEM500 field emission scanning electron microscope.

[0045] IV. Test Result Analysis

[0046] 4.1 Analysis of Moisture Absorption and Quick-Drying Performance

[0047] 4.1.1 Hygroscopicity Analysis

[0048] Hygroscopicity is used to evaluate the fabric's ability to absorb water; the more water a fabric absorbs, the stronger its hygroscopicity. Water absorption rate refers to the ratio of the mass of water absorbed by a fully wetted sample when it is in a drip-free state to the sample's dry weight. Table 2 shows that the water absorption rate of the A series samples did not differ significantly from that of the B series, but all samples exceeded the standard of 100%, indicating good water absorption of the functional yarn. This is because the hydrophilic groups in the Celeson biodegradable fiber enhance the fiber's hygroscopic capacity. Water diffusion time refers to the time it takes for a water droplet to completely diffuse and penetrate the sample after touching its surface. The water diffusion time of the A series samples decreased with increasing Celeson biodegradable fiber content in the weft yarn. Except for A1 and A2, whose water diffusion times failed to reach within 5 seconds, all others met the standard. This is because the hydrophilic groups and porous structure of the Celeson biodegradable fiber improve the hygroscopicity and moisture-wicking properties of the samples. The wicking height refers to the height to which water rises along a sample within a certain time through capillary action when the sample is vertically suspended and one end is immersed in water. According to the national standard for quick-drying and moisture-wicking fabrics, the wicking height must be no less than 90 mm; the greater the wicking height, the better the fabric's moisture-wicking properties. Table 2 shows that A1 to A9 all meet the standard, and the wicking height is greatest when the content of Celesite staple fiber in the weft yarn is the highest. This is mainly because Celesite biodegradable fibers have a porous structure, which increases the specific surface area of ​​the fiber, enhances the capillary effect, and accelerates water transport.

[0049] Table 3 shows that the moisture absorption performance of the B series is ranked as B4>B5>B3>B2>B1. The fabric with an eight-end satin weave has the best results in terms of water absorption rate, drip diffusion time, and wicking height. The results indicate that when the yarn material, weft ratio, and warp-weft density are constant, the larger the float length of the fully formed weave and the better the moisture absorption performance of the fabric.

[0050] Table 2. Moisture absorption results of Series A tests

[0051]

[0052] 4.1.2 Analysis of quick-drying properties

[0053] Quick-drying ability refers to the fabric's ability to expel moisture; the more moisture expelled, the stronger the quick-drying ability. Evaporation rate refers to the mass of water evaporated per unit time in the sample after a water droplet diffusion test. As shown in Table 4, the evaporation rates of the A series samples are all no less than the standard 0.18 g / h, and the evaporation rate generally increases with the increase of the content of the weft yarn in the celery biodegradable fiber. Because the pores of the celery biodegradable fiber itself increase the specific surface area of ​​the fiber, the water evaporation area becomes larger. Therefore, adding celery short fiber yarn to the fabric can accelerate the moisture evaporation rate of the fabric. Moisture permeability refers to the mass of water vapor passing through a unit area of ​​the sample in a specified time under certain temperature and humidity conditions. In the A series, the moisture permeability test results are similar, indicating that the correlation between moisture permeability and the content of celery short fiber yarn is small.

[0054] Combining Tables 1 and 5, it can be observed that the evaporation rate is higher for eight-end satin weave and lower for 2 / 1 twill weave in Series B. This is because the 2 / 1 twill weave has shorter floats and smaller gaps between yarns, affecting the evaporation rate even with a thinner fabric. Although the honeycomb weave has an uneven surface and a relatively large contact area with air, its thickness is also greater, resulting in a lower evaporation rate. Among the Series B fabrics, eight-end satin weave offers the best moisture permeability. When yarn material, weft-to-roll ratio, and warp-weft density are constant, a larger full-weave structure with longer floats leads to higher moisture permeability. This is because increased gaps between yarns allow moisture to pass through the fabric more easily.

[0056]

[0057] Table 5 Results of quick-drying properties of Series B samples

[0058]

[0059] 4.2 Analysis of Ease of Stain Removal

[0060] The test results were evaluated using the easy-to-clean wiping method. If the initial color difference before wiping was no higher than level 3, and the color difference after wiping was level 3-4 or higher, then the fabric was considered easy to clean. Figure 1 It can be seen that the color difference grade after wiping in the A series increases with the increase of Celesin biodegradable fiber. Due to the excellent hydrophilicity of the hydrophilic groups and porous structure of Celesin biodegradable fibers, the interfacial tension between the oil / fiber phase is strong when the sample comes into contact with water, making it easy for the dirt to separate from the sample through external mechanical action. Figure 2 It can be seen that all five fabrics with different weave structures in series B meet the requirements for easy-to-clean fabrics. However, the sample with a smooth surface has better easy-to-clean performance, while the sample with a honeycomb weave structure has weaker easy-to-clean performance than the other four. This is because the surface of honeycomb weave fabrics is uneven and easily traps dirt, and it is difficult to wipe all the soiled parts of the fabric when using the wiping method.

[0061] 4.3 Analysis of the Degradation Degree of Celes fiber in natural soil

[0062] Depend on Figure 3 As shown in (a) and (b), the surface layer of Celes' biodegradable fiber gradually detached three months after burial, compared to before burial. Observation Figure 3 (c) and (d) Ordinary polyester fibers showed no significant changes after being buried in the soil compared to before burial. Although Celes biodegradable fibers did not completely degrade in the soil after three months, they showed a more significant degradation trend compared to ordinary polyester fibers.
